Linear LT3689EMSE-5#PBF 700mA Step-Down Regulator with Reset & Wat...
£5.04  

Linear Technology NiMH/NiCd Battery Chargers - Linear Technology LT3689EMSE-5#PBF, The Linear Technology LT3689 is an adjustable frequency (350kHz to 2.2MHz) monolithic step-down switching regulator with a power-on reset and watchdog timer. The regulator operates from inputs up to 36V and withstands transients up to 60V. Low ripple Burst Mode operation maintains high efficiency at low output current while keeping output ripple below 15mV in a typical application, with input quiescent current of just 85A. Shutdown circuitry reduces input supply current to less than 1A while EN/UVLO is pulled low. Using a resistor divider on the EN/UVLO pin provides a programmable undervoltage lockout. Current limit, frequency foldback and thermal shutdown provide fault protection. The reset and watchdog timeout periods are independently adjustable using external capacitors. Tight accuracy specifications and glitch immunity ensure reliable reset operation of a system without false triggering. The open collector RST will pull down if output voltage drops 10% below the programmed value. The watchdog timer is pin-selectable for window or timeout modes. In timeout mode, WDO pulls low if too long of a period passes before a watchdog transition is detected. In window mode, the LT3689 monitors for WDI falling edges grouped too close together or too far apart. Linear LT3689EMSE-5#PBF 700mA Step-Down Regulator with Reset & Watchdog MSOP-16
